Only .1 sec faster than the c7z? That doesn’t seem right.

Same driver, same time of day, same track for the C7Z?

(Assuming optimal tire choice for each car or same tires for each car?)

larryfdx

Not sure which tires the C7 was using.

If C7Z was participating in the same time , same weahther, with same driver, it will be slower .. however Cup 2R is usually affected by cold weather more than cup 2

Agreed. The optimal temperature would be something else entirely. But that speed and entry into turn 8 in the cold is remarkable. That is a huge level of risk for a $400,000.00 car (GT3RS) and for a $275,000.00...or so... Z07!

Love the way they made this video. At every corner comparing how each car does. Worth watching......

They mentioned it was a really cold day. Low tire grip, especially for the Cup2Rs. Anything under about 50F is going to really impact their grip.

Higgs Boson

not only was it cold, the asteriks says "Freezing" which to me indicates below 32F.

only worse condition would be raining....

very impressive especially without the massive downforce numbers of the RS, no doubt helping it relatively even more in the cold.

LowcountryVette

fair enough. I didn’t actually watch it , just assumed since they threw up a leaderboard they tried for similar conditions

Really great video. Loved the explanations about what was happening on each turn and how each car was reacting to the track.

Results were as expected. The GT3RS is the king of the track. That aero is insane. But the Z06 is stunningly impressive. Far cheaper, far less aero, far more creature comforts, far more livable, and still right on the GT3RS's tail!

This agreed

Everyone know that Randy is a Porsche guy (not only a personal fan but substantially more seat time in P-Cars vs. others) yet the GT3RS was still only .6 seconds quicker and that is after he admitted some issues with the Z06 brakes. Too be 100% honest I didn't think the Z06 would be withing 2 seconds of the Porsche given the RS is basically just a stripped down race car with a license plate. Before all of these side by side tests were done so many on this forum were touting the Z06 could not get under the 7min mark at the "ring" an how it would get embarrassed by the standard GT3. We still don't know about the Ring time but we can assume now it should be under 7min mark and we know that it would handle the GT3 without much worry. Before the forum Porsche Fanboys jump on me, that is not taking anything away from the GT3RS it really should be viewed on how well Chevrolet got the Z06 right on its first try. I know only hypothetical but image if Chevy made an "RS" version of the Z06. Cut ~300lbs off from it, forgot about the need for golf clubs so it could reconfigure with better aero and gave a more optimal 4-5 gearing....and they did all of that in a car that stickered under $200K. Can you imagine the beating that car would put on every other Supercar costing 2, 3 and 4X the price!!

Its a great time to be a car lover!

GM needs to release a more serious Z06 that has active aero. But they will probably save that for the top tier Vettes. Its crazy how the CSL was out braking the Z06 in some of the corners, those things are impressive, but insanely over priced imo. It might have had to do with the tires being better for the cold compared to the Cup2R.

gtrguy

great video but why do these tests always need asterisks due to weather, tires, etc? would love to see just one test where weather is good, cars working properly, tires the same, etc.

Higgs Boson

because they test them when they can get them.

1985 Corvette

I’m a Corvette guy til I die and I’ve never been a Porsche guy, but they just overall win at everything. They do so much more with so much less. Selling 300 and 400 horsepower cars to customers for decades and people can’t get enough of them. I’ve never been on a Porsche forum with a new model reveal and seen, “if the horsepower number doesn’t start with a 7 or 8, it’s a fail”. With just 500 horses, they can produce something like this. Amazing.

They also have the wherewithal to keep their track oriented cars focused on track duty, not daily duty. That’s where Corvette drops the ball big time. Every model, even the supposed hardcore model has to wear every hat and be comfy and appealing everyone. It’s like Chevrolet is afraid they’re going to hurt feelings and lose money if they have that one, “it’s not the one for you” hard edge track car in the lineup.

Yeah I would bet its near impossible to get something like this set up and have everything just be consistently perfect. Book the track when its available. Roll with the cars the manufacturers will give you on that day. Weather is going to do whatever the weather is going to do.

Higgs Boson

What you say is true but needs context. There are 26 iterations of 911 to build online today. There are 4 Corvettes (Stingray/Z06 and Coupe/Vert). This leaves a LOT more capability to create niche versions, in fact thats exactly what all those 911s are.

Of course even the Z06 has to appeal to a wider audience, it is the GTS, Targa, GT3, Cab, Coupe, etc all in one.

With that formula in place, Porsche sold 10k total 911s in 2022 (9800 in 2015) and GM sold 37k Corvettes in 2022 (34k in 2015 even with such a "limited unfocused" selection.
Porsche sold 70k cars last year and GM sold 2.2 million

I just don't think it's realistic to hope GM matches Porsche shot for shot because that's just not what they do. Porsche is never going to sell the volume either. This is also why there are different car brands and models and choices; just because it may not be from one given manufacturer, whatever you want is available from somewhere.

Spot on analysis Higgs Many of us want GM to build a really track focused version as Porsche has done with the RS variants. So as car folks we should tip our hats and give them credit for building a model for basically every different need/type of driver. It is truely wonderful that a company can fullfill a really specific niche as Porsche as done! Although I have absolutely nothing against Porsche (or any manufacturer for that matter) I must admit I love watching Porsche Fanboys get their panties all twisted up and have to explain using verbal Jiu Jitsu why there uber track focused GT cars are getting beat and/or barely winning against a car that is $100-200K LESS!

If you take all bias and emotion out and just think for a second, you have a much heavier, not nearly track focused car with a fraction of the downforce with all of the amenities and comfort with storage front and rear etc... that is just a tad slower than one of the most track focused cars that has ever been built by a manufacturer...and WAY more expensive and WAY less practical. It is really mind boggling when you think about. The Z06/Z07 should not be in the same league as the GT3RS on the track as this is its huge selling point. It doesn't make any sense, but here we are. So again instead of crapping on Porsche lets give GM the credit they deserve for what they have given us!
